Managing Audio Books with Plex

Library Setup

I have a membership with Audible and I sometimes also get other audio book sources. Recently I experimented with combining all of my audio books into a centralized place. Since I already have a Plex server running, I thought it would be a good place to do this.

I did a little research and came across a couple of very helpful articles:

  • A Reddit article;
  • and some really detail information on GitHub;

The main points are:

  • I have a single folder to store all of my audio books. Inside the folder, each audio book is stored as an “m4b” file.
  • Ensure that audio books have a poster image and that its artist and album_artist tags are set to the author. Where appropriate, the audio book should also contain chapter metadata.
  • Download and install the Audnexus agent;
  • Create a music library on Plex by adding the audio book folder, and set the agent to Audnexus
Note the Agent setting
  • Ensure that the advanced option of “Store track progress” is checked.
Ensure that Store Track Progress is checked!

Each book in the library will be represented as an album, and the author will be mapped to album artist. Once the library is created, you can download and play the audio books from the desktop using the Plex app. However, the more common use case is to listen to the audio books while on the go.

Using Prologue to Play Audio Books

We first have to download the Prologue App. I did not get any of the In-App premium functionality, and just stayed with the free version.

Point the app to my Plex server’s URL, and all the audio books from the library should now be accessible and playable on the iPhone or iPad with chapter, bookmark, and last-left-position support.

This is a really neat solution, and I am impressed how Plex and Prologue together formed a dynamic duo in this manner.

PlexConnect with Apache 2

To get Plex working on my old Apple TV 3, I had to setup a PlexConnect server that bridges the Apple TV 3 to the Plex Media Server. Previously I discussed about hosting the PlexConnect server on a virtual machine (VM) because the host that PlexConnect is running on must be listening to port 80 and 443. Having a virtual machine is a big nuisance, because the VM may not be up and running. I even try to host PlexConnect on a dedicate Raspberry Pi so that I can leave it on, but that proved to be too slow.

I do have a Network Attached Storage (NAS) server so it will be ideal to run PlexConnect on that, but the NAS server is running Apache 2 which is already using port 80 and 443. Eureka! How about running a reverse proxy that points to an instance of PlexConnect running on the NAS that is running on a separate port. A quick Google search for the term “PlexConnect and Apache 2” found this page on GitHub. The article turned out to be extremely helpful.

I downloaded PlexConnect as before and created the certificates.

cd /home/kang

wget https://github.com/iBaa/PlexConnect/archive/V0.6.tar.gz

tar zxvf V0.6.tar.gz 

mv PlexConnect-0.6 PlexConnect

rm V0.6.tar.gz

cd PlexConnect/assets/certificates

openssl req -new -nodes -newkey rsa:2048 -out trailers.pem -keyout trailers.key -x509 -days 365 -subj "/C=US/CN=trailers.apple.com"

openssl x509 -in trailers.pem -outform der -out trailers.cer && cat trailers.key >> trailers.pem

I then have to tell PlexConnect the following:

  • Do not enable DNS since we already have a DNS server running;
  • Do not enable automatic IP detection because it will get the wrong VPN client IP, instead I hard coded the 192.168.168.198 IP;
  • Disable SSL server because this will be handled by Apache 2;
  • Change the port number from 80 to 18080

The final Settings.cfg configuration file looks like this with the changed values highlighted in bold:

[PlexConnect]
enable_plexgdm = True
ip_pms = 192.168.178.10
port_pms = 32400
enable_dnsserver = False
port_dnsserver = 53
ip_dnsmaster = 8.8.8.8
prevent_atv_update = True
intercept_atv_icon = True
icon = movie-trailers
enable_plexconnect_autodetect = False
ip_plexconnect = 192.168.168.198
hosttointercept = trailers.apple.com
port_webserver = 18080
enable_webserver_ssl = False
port_ssl = 18443
certfile = ./assets/certificates/trailers.pem
allow_gzip_atv = False
allow_gzip_pmslocal = False
allow_gzip_pmsremote = True
loglevel = Normal
logpath = .

I had to configure my firewall’s local DNS to resolve trailers.apple.com to my NAS server, which is 192.168.168.198. This was pretty simple on my UniFi Universal Secure Gateway (USG).

The Apache 2 configuration files needed to be setup with the reverse proxy for both port 80 and 443. To do this I added the following VirtualHost settings.

<VirtualHost *:443>
        ServerName trailers.apple.com

        SSLEngine on
        SSLProxyEngine on
        SSLCertificateFile "/home/kang/PlexConnect/assets/certificates/trailers.pem"
        SSLCertificateKeyFile "/home/kang/PlexConnect/assets/certificates/trailers.key"

	<Proxy *>
		Require ip 192.168.168.0/255.255.255.0
	</Proxy>

        RequestHeader set User-Agent AppleTV
        ProxyRequests Off
        ProxyPass / http://avs.localdomain:18080/ nocanon
        ProxyPassReverse / http://avs.localdomain:18080/
</VirtualHost>
<VirtualHost *:80>
        ServerName trailers.apple.com
        SSLEngine off

	<Proxy *>
		Require ip 192.168.168.0/255.255.255.0
	</Proxy>

        RequestHeader set User-Agent AppleTV
        ProxyRequests Off
        ProxyPass / http://avs.localdomain:18080/ nocanon
        ProxyPassReverse / http://avs.localdomain:18080/
</VirtualHost>

I also needed to enable the headers module.

sudo a2enmod headers

We then needed to create a new systemctl service for PlexConnect. I had to create a plexconnect.service file in /etc/systemd/system with the following contents.

[Unit]
 Description=Plexconnect
 After=plexmediaserver.service
 
 [Service]
 Type=simple
 ExecStart=/usr/bin/python /home/kang/PlexConnect/PlexConnect.py
 User=root
 Group=root
 Restart=on-failure
 RestartSec=15
 StartLimitInterval=10s
 StartLimitBurst=3
 
 [Install]
 WantedBy=multi-user.target

The final steps are:

  • Check the Apache configuration file
  • Restart Apache
  • Start PlexConnect
sudo apache2ctl configtest

sudo systemctl restart apache2

sudo systemctl start plexconnect.service

Went to the Apple TV 3, and reconfigure the DNS to auto, removed the old profile and re-add http://trailers.apple.com/trailers.cer as the new profile. I discussed in my previous blog.

After signing into my Plex account, and testing various Plex media sources with the Trailers app, as well as trying out YouTube and the Prime Video app, everything is good! The VM is no longer required and we declare victory!
